Port and Port Extender
 Inspection. Before installing the Port Extender and Port, visually inspect the o-
rings for dirt or other foreign matter that may compromise the seal. Do the same
with the bulkhead face and Port bore where the o-rings seal. See the document
“Housing Care and Maintenance Guide” for more details.
 Lubrication. Lubricate the Port o-ring with silicone grease. Also liberally lubricate
the Port bore. This will greatly aid installation of the Port.

E Port Extender o-ring. It is silicone
material and lubricant may cause damage. Only the BLACK and YELLOW o-rings
are safe to lubricate.
 Install the Port Extender. Position the Port Extender over the entire lens / LGD’s
and secure to the front bulkhead with 4 screws. Tighten the 4 screws firmly.
 Install the Port Mask. If you have need of a port mask to control reflections (see
subsequent section on this topic), install it now. It should slip over the front of the
lens with just enough tension to remain in place.
 Install the Port. The Port will mate with the Extender when rotated 90 degrees
from its normal position. Insert the Port into the port opening, ensuring it is fully
seated prior to rotation. Once seated, rotate either direction until the shade is
aligned top and bottom.
 Verify seals. Inspect the Port Extender and Port are fully seated with no gaps.
Install the Port Extender, Mask and Port.
